Abstract
- A hybrid self-powered synchronous electric charge extraction (HSP-SECE) interface circuit based on double stack resonance is presented in this paper. The proposed HSP-SECE interface circuit can simultaneously extract energy from piezoelectric transducer (PZT) and thermoelectric generator (TEG) when the peak open-circuit voltage of the PZT is detected by passive peak detector. The output power of the proposed interface circuit can reach three times of that of full-bridge rectifier circuit at the maximum power point, and the maximum efficiency of harvesting thermoelectric energy can reach 76% at 200 mV of the open-circuit voltage of the TEG. The simulation and experimental results show the superiority of the HSP-SECE circuit. [ABSTRACT FROM AUTHOR]
